Hi i'm getting below error when I run my gulp tasks
[16:27:46] Starting 'watch-folder'... [16:27:46] 'watch-folder' errored after 456 ms [16:27:46] Error in plugin "gulp-ssh" Message: Handshake failed: no matching key exchange algorithm Details: level: protocol domain: [object Object] domainThrown: true

Here is my code

`var fs = require('fs');
var gulp = require('gulp')
var GulpSSH = require('gulp-ssh');
var path = require('path')
const homedir = require('os').homedir();
var watch = require('gulp-watch');

const config = {
host: 'remotehost.com',
port: 40022,
username: 'username',
privateKey: fs.readFileSync(path.join(homedir+'/.ssh/id_rsa'))
};

const gulpSSH = new GulpSSH({
ignoreErrors: true,
sshConfig: config
});
const excludeddirs = "'!/node_modules/','!/logs/','!/allure-report/','!/allure-results/','!/dist/','!/reports/','!/testresults/'";
const watchsource = './src/specs';
const rootdest = '/tmp/GulpProjects/mydesmond/e2e/';
const watchdest = rootdest+'/src';

gulp.task('copyrootfiles', function() {
return gulp
.src(['.',excludeddirs])
.pipe(gulpSSH.dest(rootdest))
});

gulp.task('watch-folder', function() {
gulp.src(watchsource + '/**/*', {base: watchsource})
.pipe(watch(watchsource, {base: watchsource}))
.pipe(gulpSSH.dest(watchdest));
});

Seems like you are using "ssh2": "~0.5.5"
You should use latest ssh2 package.
Our servers allow only "curve25519-sha256@libssh.org" algorithm
but the the pakage you are using doesn't allow that
